ABSTRACT

Today, many full-time students spend one, two, or more additional years completing a 2-year associate or 4-year bachelor degree. In order to reduce this time frame, many institutions are utilizing a 15 to Finish campaign to encourage full-time students to enroll in 15 credits each semester. The first purpose of this study was to examine if there is a relationship between the number of credit hours enrolled in the first semester and the number of credits earned at the end of the first year. Concurrently, it examined how a student’s initial academic momentum (i.e., the number of credit hours earned in the first year) relates to student persistence and degree completion. The second purpose was to determine if there was a relationship between a student’s socioeconomic status and the number of credit hours enrolled in the first semester—and if it is feasible for low-income students, who primarily attend community colleges, to afford additional credit hours. The results showed that more students who earned 30 credit hours in the first academic year persisted to the second year and earned a degree than students who did not earn 30 credit hours. Also, the results showed that the majority of low-income community college students had enough Federal Pell Grant funds to pay for the additional tuition cost. Given these results, practical and policy implications are discussed.  相似文献

Rats trained in one context to use stimuli arising from food deprivation as discriminative signals for shock were tested in other contexts to assess the basis of conditioned responding (i.e., freezing or behavioral immobility). In Experiment 1, discriminative control by 24-h food-deprivation cues failed to promote transfer responding in a test context that had no association with shock. This indicated that food deprivation cues had little direct excitatory power. However, transfer of behavioral control by 24-h food-deprivation cues was obtained in a context paired with shock only when the rats were 19 h water deprived. This finding agrees with the idea that food-deprivation cues become conditioned modulators of the capacity of external stimuli to activate their association with an unconditioned stimulus. In Experiment 2, rats trained to use 24-h food-deprivation cues as signals for shock exhibited significantly greater transfer performance when the transfer context had undergone partial extinction relative to when the transfer context had undergone only simple excitatory training. This finding with deprivation cues and transfer contexts (1) paralleled earlier results obtained with discrete (auditory and visual) conditioned modulators and transfer targets, and (2) posed difficulties for associative summation and generalization interpretations of transfer performance.  相似文献

This paper explores how opposite sides of the abortion debate employ a discourse of endangerment to mobilise political support for their ideologies about black women’s bodies. I examine the role of black women within that rhetorical strategy through various rhetorical artefacts. To analyse these artefacts, I employ the theoretical framework of ideological or ideographic criticism. This framework helps us see how the artefacts used by both pro and anti-choice movements ‘condition’ the audience not merely to adopt a set of ‘beliefs and behavior, but a vocabulary of concepts that function as guides, warrants, reasons, or excuses for behavior and belief’. Though the two sides of the abortion debate differ in their overt political views, they turn out to share an implicit ideology about black women. This ideology prevents the voices of black women from being heard and valued in a debate that is nonetheless focused on black women’s bodies.  相似文献

This study analyzes post-secondary schooling decisions of high-school graduates using a human-capital framework. Unlike most studies, which consider only college or no school, the current analysis considers the alternative of post-secondary occupational schools as well as four-year and two-year colleges. The model is tested using a multinomial logistic approach on state aggregated data for 1976. Cross-price elasticities reveal that post-secondary occupational schooling is a relevant substitute investment for college. Own-price elasticities have the expected negative sign and income is not found to be a significant determinant of post-secondary-school attendance.  相似文献
